The SDK directory is not writable

[hoh]

I am trying to use Flutter on NixOS. When trying this repository, after overriding the issue in #8 using --ignore-deprecation, I am facing the following error:

> Failed to install the following SDK components:
      build-tools;28.0.3 Android SDK Build-Tools 28.0.3
  The SDK directory is not writable (/nix/store/95n2vl2aipq7295wrc7ins6j953kzsww-androidsdk/libexec/android-sdk)

The complete log is:

user@host ~/flutter_nix_hello_world (master)> nix-shell

[nix-shell:~//flutter_nix_hello_world]$ flutter build apk --ignore-deprecation
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Warning
──────────────────────────────────────────────────────────────────────────────
Your Flutter application is created using an older version of the Android
embedding. It is being deprecated in favor of Android embedding v2. Follow the
steps at

https://flutter.dev/go/android-project-migration

to migrate your project. You may also pass the --ignore-deprecation flag to
ignore this check and continue with the deprecated v1 embedding. However,
the v1 Android embedding will be removed in future versions of Flutter.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The detected reason was:

  /home/user/flutter_nix_hello_world/android/app/src/main/AndroidManifest.xml uses
  `android:name="io.flutter.app.FlutterApplication"`
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

This app is using a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to migrate this app to the V2 embedding.
Take a look at the docs for migrating an app: https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects

Well, actually, refreshing the flake.lock file, the errors appears again with the latest android simulator (33.1.6)
